Good eyesight would be appropriate for scavengers that keep an eye out
for carcasses in the distance... either by sighting large carcasses
directly or the pterosaurs above heading in the direction of
carcasses.

Smell can be useful too if downwind.

Wonder if there was an equivalent of circling vultures... New world
vultures have a good sense of smell used in carcass detection, but
that probably reflects more the differences between open areas and
forested ones.
